- 6. What is the difference between if (p { }? == q) {...} and if (*p == *q)arrow_forwardGiven a list of integers, you want to know whether it is possible to divide the integers into two sets, so that the sum of one set is odd, and the sum of the other set is a multiple of 10. Every integer must be in one set or the other. You can write a recursive helper method that takes any number of arguments and then call it inside the method, but you cannot use any loops. Test cases: oddAndTen([5, 5, 3]) true oddAndTen ([5, 5, 4]) oddAndTen ([5, 5, 4, 1]) false truearrow_forwardUse the right loop for the right assignment, using all the follow- ing loops: for, while without hasNext(), while with hasNext() and do-while. So I cannot use array. it has to be done in java.arrow_forward
- The word ladder game was invented by Lewis Carroll in 1877. The idea is to begin with a start word and then change one letter at a time until you arrive at an end word. Each word along the way must be an English word. For example, starting from FISH, you can arrive at MAST through the following word ladder:FISH, WISH, WASH, MASH, MAST Write a program that uses recursion to find the word ladder given a start word and an end word, or that determines no word ladder exists. Use the file words.txt that is available online with the source code for the book as your dictionary of valid words. This file contains 87,314 words. Your program does not need to find the shortest word ladder between words; any word ladder will do if one exists. list aalii aardvark aardvarks aardwolf aba abaca abaci abacist aback abacus abacuses abaft abalone abalones abamp abampere abandon abandoned abandonee abandoner abandonersarrow_forwardCorrect answer will be upvoted else Multiple Downvoted. Computer science. pick a non-void adjacent substring of s that contains an equivalent number of 0's and 1's; flip all characters in the substring, that is, supplant all 0's with 1's, as well as the other way around; turn around the substring. For instance, think about s = 00111011, and the accompanying activity: Pick the initial six characters as the substring to follow up on: 00111011. Note that the number of 0's and 1's are equivalent, so this is a lawful decision. Picking substrings 0, 110, or the whole string would not be imaginable. Flip all characters in the substring: 11000111. Invert the substring: 10001111. Find the lexicographically littlest string that can be gotten from s after nothing or more tasks. Input The primary line contains a solitary integer T (1≤T≤5⋅105) — the number of experiments. Every one of the accompanying T lines contains a solitary non-void string — the input string s for…arrow_forwardYou have a card on which the letter J is written on one side and K on the other. You want to seeall of the possible ways the card will land if you drop it n times. Write a recursive method thatprints each session of dropping the cards with J's and K's. For example if you drop it 4 times in agiven session, all possible ways to drop it are as follows (in exactly the specified order): J J J JJ J J KJ J K JJ J K KJ K J JJ K J KJ K K JJ K K KK J J JK J J KK J K JK J K KK K J JK K J KK K K JK K K Karrow_forward
- Practice / First Non-Repeating Vowel Given a string, write a method to find the first non-repeating vowel (a, e, i, o, u) in it and return its index. ● If it doesn't exist, return -1. ● Assume that all the characters of the String is lowercase. Do not use String class functions other than charAt() and length() You can also try to solve with Map data structure like using a Map variable. ● Example input: google output: 5 explanation: only e is non-repeated vowel and it's index is 5 Example input: mood output: -1 explanation: o is repeated, no non-repeating vowel. Example input: responsible output: 4 explanation: e is repeated, o and i are not repeated, o is the first non-repeating vowelarrow_forward1. Write a recursive method expFive(n) to compute y=5^n. For instance, if n is 0, y is 1. If n is 3, then y is 125. If n is 4, then y is 625. The recursive method cannot have loops. Then write a testing program to call the recursive method. If you run your program, the results should look like this: > run RecExpTest Enter a number: 3 125 >run RecExpTest Enter a number: 3125 2. For two integers m and n, their GCD(Greatest Common Divisor) can be computed by a recursive function. Write a recursive method gcd(m,n) to find their Greatest Common Divisor. Once m is 0, the function returns n. Once n is 0, the function returns m. If neither is 0, the function can recursively calculate the Greatest Common Divisor with two smaller parameters: One is n, the second one is m mod n. Although there are other approaches to calculate Greatest Common Divisor, please follow the instructions in this question, otherwise you will not get the credit. Meaning your code needs to follow the given algorithm. Then…arrow_forwardASAP Solution needed / Solution You're given a string of words. You need to find the word "Nemo", and return a string like this: "I found Nemo at [the order of the word you find Nemo]!" If you can't find Nemo, return "I can't find Nemo :(". Examples findNemo ("I am finding Nemo !") → "I found Nemo at 4!" wwwwwwww ➡ "I found Nemo at 1!" findNemo ("Nemo is me") www findNemo ("I Nemo am") wwwwwwwww "I found Nemo at 2!" (Ctrl)arrow_forward
- public static String reversevowels (String text) Given a text string, create and return a new string of same length where all vowels have been reversed, and all other characters are kept as they were. For simplicity, in this problem only the characters aeiouAEIOU are considered vowels, and y is never a vowel. For example, given the text string "computer science", this method would return "cempetir sceunco". Furthermore, to make this problem more interesting and the result look more palatable, this method must maintain the capitalization of vowels based on the vowel character that was originally in the position that each new vowel character is moved into. For example, "Ilkka Markus" should become "Ulkka Markis" instead of "ulkka MarkIs". Use the handy utility methods in the Character wrapper class to determine whether some particular character is in upper- or lowercase, and convert a character to upper- or lowercase as needed.arrow_forwardA popular word game involves finding words from a grid of randomly generatedletters. Words must be at least three letters long and formed from adjoining letters.Letters may not be reused and it is valid to move across diagonals. As an example,consider the following 4 * 4 grid of letters: A B C DE F G HI J K LM N O P The word “FAB” is valid (letters in the upper left corner) and the word “KNIFE”is valid. The word “BABE” is not valid because the “B” may not be reused. Theword “MINE” is not valid because the “E” is not adjacent to the “N”. Write a program that uses a 4 * 4 two-dimensional array to represent the gameboard. The program should randomly select letters for the board. You may wishto select vowels with a higher probability than consonants. You may also wish toalways place a “U” next to a “Q” or to treat “QU” as a single letter. The programshould read the words from the text file words.txt (included on the website withthis book) and then use a recursive algorithm to…arrow_forwardSolution in Java Implement a method removeWord() that takes two string parameters: sentence - the sentence you are to remove a word from. word - the word you are to remove from the sentence. Your method should take a string, sentence and remove word from it. It will return a new string without word in the sentence. Examples removeWord("One two three four", "two") → "One three four" ● removeWord("Bob has a kid", "kid") → "Bob has a" (Ctrl)arrow_forward
